Definitions

  • the invention is based on an anchor for an electrical machine according to the preamble of claim 1.
  • a rotor with a shaft is already known from US Pat. No. 4,886,392, which has knurling and smooth areas on a surface of the shaft, the shaft being approximately the same in the area of the knurling and the smooth areas
  • the US-PS 4,339,873 shows a rotor shaft which has a recess in which a knurling is arranged.
  • the component which is pushed onto the rotor shaft, is arranged with its taper in the installed state in the area of the knurling.
  • the taper is created by plastic deformation of the component after the component has been pushed onto the shaft.
  • the anchor according to the invention with the characterizing features of claim 1 has the advantage over the fact that a component can be attached to a shaft in a simple manner and is held securely. Furthermore, the taper in the inner diameter of the component causes the material of the component to plastically deform in the region of the taper and flow into the knurling, thus forming a positive fit.
  • a plastic-injected magnet can advantageously be used for the component, since it is mechanically softer than the shaft. It is also advantageous that the taper is arranged in the center of the component, because the stresses around the knurling can thereby be reduced uniformly.
  • FIG. 1 shows a component that is used for an anchor according to the invention
  • FIG. 3 shows an anchor according to the invention in the assembled
  • FIG. 1 shows a component 1, which is, for example, a mechanical ball bearing or a plastic-injected magnet and, in comparison to the shaft 10 (FIG. 2), consists of a relatively softer material.
  • the component 1 has a central axis 3, which can also be the axis of symmetry, for example, and a recess 4 that extends in the interior of the component 1 in the axial direction.
  • a taper 7 is arranged centrally in the axial direction, ie in the outer region of the recess 4 the component 1 has an inner diameter Di and in the region of the taper 7 a smaller inner diameter esser di.
  • FIG. 2c shows the shaft 10 of the anchor according to the invention with an outside diameter d'a.
  • the shaft 10 is manufactured, for example, as follows. In the case of a shaft 10 with an outer diameter Da, a recess is made in the area 13 of a later knurling 11, which then has a smaller outer diameter da (FIG. 2a)). Knurling 11 is introduced in this area, as shown in FIG. 2b.
  • the knurling 11 has an outer outer diameter d'a.
  • the type of knurling is arbitrary. It can consist of longitudinal grooves, transverse grooves or crossed grooves.
  • the outer diameter Da on the shaft 10 outside the knurling 11 is, if necessary, ground or turned so that it corresponds to the outer diameter of the knurling 11, i. H. the shaft 10 has a constant outside diameter d'a. If necessary, a knurling 11, which has a larger outside diameter than Da in diameter, is reduced to Da.
  • the shaft 10 can also be hardened in sections.
  • Figure 3 shows how the component 1 is attached to the shaft 10.
  • the component 1 has an axial length that is longer than the knurling 11.
  • the inner diameter Di of the component 1 corresponds, for example, approximately to the outer diameter d'a of the shaft 10 according to FIG. 2c, ie when the component 1 is initially pushed onto the shaft 10, the component 1 is guided through the shaft 10. There may also be a slight press fit. If the component 1 is pushed further onto the shaft 10, a tension occurs or increases in the component 1 because the taper 7 is pushed onto the shaft 10 outside the knurling 11. If the component 1 is pushed further onto the shaft 10 until the taper 7 in Area of the knurling 11 is arranged, the component 1 deforms due to the press fit in the area of the taper 7, because the material of the component 1 penetrates into the depressions of the knurling 11.
  • Such an armature 15 can be used for an electric motor or an electric generator and still has, in a manner not shown, a carrier body for at least one coil or permanent magnet and, for example, a commutator.

Abstract

Lorsque l'on procède à l'ajustement serré d'une pièce sur un arbre selon la technique antérieure, une fois montée, ladite pièce conserve des tensions qui peuvent l'endommager. Un induit (15) selon l'invention comporte une pièce (1) à monter sur l'arbre (10), laquelle présente, intérieurement, un étranglement (7) qui vient s'insérer dans une partie moletée (11) de l'arbre (10), les tensions initiales pouvant ainsi s'éliminer au moins partiellement avec le temps.
